The North American Industry Classification System size standard is corrected to read $6.0 million vice $66,000. The Fleet and Industrial Supply Center (FISC) Norfolk Detachment Philadelphia intends to modify existing contract N00140-98-C-G309 with SIMCO Electronics to provide an additional six (6) months of Calibration Maintenance and Material Support Services to support the Fleet Training Center, San Diego, California, beginning 1 October 2002 and ending 31 March 2003. This action is required to provide continuity of services pending a determination by the Government on the need for a follow-on contract. SIMCO Electronics is considered the only supplier of these services at this time with the expertise, equipment and facilities that can support the immediate needs of the Government without a costly start-up period.
